position, the grain receiving lend of the cyl-L inder so that the entire cylinder will have a required amount of-slope from the grain receiving end vto the discharge end; and,rfur ther, to provide means for properly receiving and resisting' the end thrust of such cylinder when the same is so forwardly sloped, together with means for driving the cylinder. Y

l Thefullobjects and advantages of my invention will appear in connection with the detailed description thereof, andV are particularly pointed out in the claims.

In the drawings, illustrating the applica-V tion of lmy, invention in one form,-

Fi'gure 1 isa side elevational view of a wheat heater embodying my improvements. Fig..2 isa front elevation view of the same, with some parts broken away. Fig. 3 is an enlarged sectional detail view of the driving and end thrust receiving mechanism. Figs. 4, 5, and 6 are sectional detail views showing means for adjustingY and stabilizing the adjusting or grain receiving end of the wheat heater. l

As illustrated,.the vend'supports 10 and 11 have journaled therein rollers 12 and 13 uPOn which rest rings 14 and 15 of a cylinder 16 rotatably supported between said ,endvv supports on said rings. The end supports are held in properly relative position by connecting rods 17. Each of the end supports 10 andll is provided with a pair of feet 18. If the wheat heater sets upon these four feet, it will be held substantially horizontal. It is desirable, however, to adjust the grain receiving end of the wheat heater somewhat higher than the discharge end, and it is frequently desirable to change this adjustment for operating upon differentgrades of grain. To provide means for holding the heater in the proper position of adjustment, Iarrange a movable base 19 having a horizontal top 20 in combination` with a second base member 21 having a top 22 nangularly disposed in respect -to top 20 so as to be in parallel'and engaging rotation with the face 23 of foot i 18. In prac'ticea`series of secondary supports 21 are provided of varying heights so thatdiiferent degrees of Aelevation of. the end support 10 may thereby be effected, resulting in different degrees of forward slope to the cylinder 16. The top 20 of base 19 .is

provided with an elongated slot 241 through which extends a bolt 25 which enters or is secured in ythe floor or other pedestal support of the machine and which bolt extends through 'a slot 26 in top22 of base member 21 and through the wall 23 of foot 18 having threads on the end thereof and nut 27. Within the space 28 below the top 22 of base 'member 21, and resting upon the top 20 of base member 19 is a support or socket piece 29 which provides a fulcrum for the lower end of a bolt SOthreaded through the wall23 of foot 18. vrAfter lthe second base member 21 has been put in position'and the nut 27 and bolt 30 have been tightened to the desired extent, the parts will be held ment ofthe receiving end of the wheat heater will be properly effected. In order to change the base member 21 for a higher or lower member as desired, the nut 27 is withdrawn from bolt 25, and bolt 25 removed. The bolt 30 is then screwed up so as' to lift the foot 18 from oif the base member 21. This is then pushed over, the bolt 30 traveling along slot 26 until the inner wall of member 21 contacts with the socket piece 29 and a new member of the desired height. having therein a suitable socket Y piece, is inserted in the space fromwhich the l,n 'ien'iber 21 has been removed.Z The bolt 30 v is then unscrewed permitting the foot 18 to rest upon the newly inserted base member.

' rigidly together as a unit and the adjustbeveled rollers 311 journaled upon studs 35, :tast on a port-ion oit the end casting 11. @ne of the rollers 13, as shown in Figs. 1 and 3, is itast on a shatt- 36 having on one end a spur pinion 37 meshing` with spur gear 31 and on the other end a pulley 38 by which shaft 36 and pinion 37 are driven, thereby rotating the cylinder 16. lt will be noted that the cylinder' 16 rests by gravity only upon rollers 12 and 13. It 'follows that when the cylinder is in the forwardly inclined position shown in Fig. 1, it will tend to move forward. rlfhis brings the face 33 in contact with the angularly positioned rollers 34, thus resisting the ,end thrust tendency of the cylinder and holding it in a fixed position longitudinally while permitting the utmost freedom. of revolution.

l claim:

1. A wheat heater comprising a rotary cylinder, means for supporting said cylinder in an inclined posit-ion including a. foot member' at one end o't said cylinder having an inclined bottom, a primary base member adapted to rest upon. the floor underneath and spaced from said foot member, and a secondary base member adapted to be inserted between said primary base member and said foot member, said secondary base member having an inclined top to cooperate with the inclined bottom ot said toot member.

A wheat heater comprising a rotary cylinder, means Yfor supporting said cylinder in an inclined position including` a foot member at one end of said cylinder having an inclined bottom, a primary base member adapted to rest upon the door underneath and spaced from said foot member, a seeondary member adapted to be inserted between said primary base member and said `toot member, said secondary base member having an inclined top to cooperate with an inclined bottom of said footmember, means for liftingsaid `toot member to permit insertion of different sized secondary base members, and means ior holding said primary and secondary base members in position beneath said -toot member.

3. A wheat heater comprising a rotary cylinder, means for supporting said cylinder in an inclined position including a foot member at each end, the foot member which is at one end being` provided with a screw threaded. hole in its bottom, a screw threaded bolt adapted to be screwed into said screw threaded hole from above, a primary base member adapted to rest upon the floor underneath and spaced from said foot member, a secondary base member adapted to be inserted between said primary base member and said 'foot member, said secondary base member having an elongated slot in its top, and a relatively small support adapted to rest upon the primary base member in position to be engaged by said screw threaded bolt for lifting said foot member to permit insertion of different sized secondary base members.

4f. A wheat heater comprising a rotary cylinder, means for supporting said cylinder in an inclined position including a foot member at each end, the toot member which is at one end being provided with a screw threaded hole in its bottom, a screw threaded bolt adapted to be screwed into said screw threaded hole from above, a primary base member adapted to rest upon the licor underneath andspaced from said foot member, a secondary base member adapted te be inserted between said primary base member and said foot member, said secondary base member having an. elongated slot in its top, a relative small support adapted to rest upon the primary base member in position to be engaged by said screw threaded bolt for lifting` said foot member to permit insertion of different sized secondary base members, said toot member being provided with a second hole in its bottom, a bolt anchored beneath said primary base member and having a screw threaded upper end adapted to extend loosely through said second hole, and a nut adapted to be screwed upon said screw threaded end to hold said primary and secondary `base members in position beneath said foot member.
